Avoid Inbox Fatigue: The Right Email Frequency for Small Business
Summary: Email frequency directly affects engagement, unsubscribes, and deliverability. Most small businesses should start with one email per week and test higher cadence only for engaged segments. Keep unsubscribe rates below 2% and spam complaints under 0.3% to stay in inboxes. Use segmentation and automation to send relevant content, and run re-engagement campaigns at 60–90 days of inactivity to maintain list health.

Daily sends risk triggering complaints unless they’re short bursts for sales or launches. A simple rule: if your unsubscribe rate stays below 2% and your spam complaints stay below 0.3%, your cadence is probably fine. What Are the Best Practices for Segmenting Your List?
